' ADOLPH ALBERT KLEIN, OF PHILADELPHIA, PENNSYLVANIA.

ELEVATOR- HATCHWAY.

SPECIFICATION forming part of Letters Patent No. 333,526, dated January 5, 1886.

Application filed June 1, 1885. Serial No. 167,190. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH A. KLEIN, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Elevator-Hatchways, of which the following is a specification.

My invention has reference to elevatorhatchways; and it consists in certainimprovements therein, all of which are fully set forth in the following specification and shown in the accompanying drawings, which form part thereof.

The object of my invention is to provide suitable mechanism by which the ascending and descending cage or platform may automatically open or close the hatch-doors with a speed commensurate with the travel of the cage.

My object is also to provide the doors with guide-strips for the cage, which, when the said doors are raised, lie close thereto and form a continuous guideway without the least mutilation of the doors.

In the drawings, Figure 1 is a sectional elevation of an elevator, showing two floors, and in which the cage has opened one of the hatchways in the act of descending or ascending, and shows the other of said hatchways closed. Fig. 2 is a sectional elevation on line a: x of part of same; and Fig. 3 is a perspective view of one of the hatch-doors raised, showing the continuous guide.

A are the vertical guide-posts. D are the guides thereon, which may be either plain or made like racks, and B are the hatchways.

O are the hatch-doors, which are hinged in the usual manner, and when raised fit into the recess 0 in the guide-posts. These hatchdoors are provided at their upper or free ends with a small rigid section, E, of the guide, which is connected by the two sections F F and hinges f with the fixed guide D on the posts A. From this it is seen that when the door is down the section F F assumes the positions indicated in the lower part of Fig. l, but when raised these sections F F lie up flat against the door, as indicated in the upper part of Figs. 1 and 3. These hatchdoors are raised by chains or wire cables G, which pass over fixed pulleys H and around movable pulleys I to fixed supports K. The pulleys I are loosely journaled in the ends of the links J, the lower ends of which are guided by wheels S, which run in the vertical guides L, secured to the side of the guide-posts A, and the upper ends of the said links are hinged at N to levers M, in turn hinged at m upon guide-posts A.

The cage P, in descending, strikes the lever M, depressing the link J, the lower end of which is guided by the guideway L and roller S, and depresses the chain or wire cable G, doubling it upon itself, and as the upper end thereof is made fast the lower end is drawn up, raising the hatch-door with it, which action simultaneously therewith straightens the guides F F, and the cage P descends through the hatch-door thus open. In ascending, the curved iron R,secured to the cage, presses upon the guide-strips Q, (see Fig. 3,) raising the door simultaneously with its upward movemen-t, the vertical parts r of the said guide holding the doors open after being raised.

I- do not limit myself to the details of construction, as they may be modified in various ways without departing from my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A hatch-door for elevators, hinged to the hatchway at one side, in combination with the guide-posts and the guides, and a folding guide hinged to said door and the guide-post, and adapted to lie flat against the door when raised, being longer than the width of the door, and completely filling up the space in the fixed guide necessarily cut away for the reception of the hatch-door when raised, substantially as and for the purpose specified.

2. A hatch-door having the hinged guidesections F F, in combination with the fixed guide D, one end of said sections being hinged to the door and the other end to the guide D, substantially as and for the purpose specified.

3. The hatch-door 0, having the fixed guidesection E, in combination with the fixed guide D and hinged sections F F, connected, respectively, to section E and guideZD, substantially as and for the purpose specified.

4. A hatch-door made, rectangular and without mutilations, in combination with a fixed mutilated guide for the cage and a folding or hinged guide carried by said door and adapted to completely span the mutilated or cut-away portionof the fixed guide, thereby making a continuous guide without leaving any aperture in the door when closed, substantially as and for the purpose specified.

5. The combination of the hatchway B with the hinged door 0, the chain or cable G, guideroller H for the cable, over which it is drawn by the link J, link J, a vertical guide for said link, lever M, and cage P, one end of the link being secured to the lever, and the other end being arranged to actuate the chain or cable to raise or lower the door, substantially as and for the purpose specified.

6. The combination of the hatchway B and hinged door 0 with the chain or cable G, guide-roller H, link J, having rollers I and S, guide L, lever M, and cage P, substantially as and for the purpose specified,

7. The combination of the hatchway B and hinged door 0 with the chain or cable G,

guide-roller H, link J, having rollers I and S,
